ALBERT MARION GRUBBS, OF FOREST GROVE, OREGON.

RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 444,633, dated January13, 1891.

Application filed September 23, 1890. Serial No. 365,915. (No model.)

To all whom, t may concern.-

Be it known that I, ALBERT MARION GRUBBS, a citizen of the UnitedStates, residing at Forest Grove, in the county of Washington and Stateof Oregon, have invented a new and useful Railroad-Switch, of which thefollowing is a specification.

This invention relates to railroad-switches; and it has forits object toconstruct a switch which shall be simple and durable, and in which thewheels of passing .rolling-stock may cross the main-line rails withoutthe necessity secured a guard-rail19.

for cutting the latter.

The invention consists in the improved construction and arrangement ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and pointed out in the claim.

In the drawings, Figure 1. is a plan viewof a railway-switch embodyingmy improvements, showing the switch closed. Fig. 2 is a plan viewshowing the switch open. Fig. 3 is a sectional view taken on the line 22 in Fio. 1.

Ilike numerals of reference indicate like parts in all the figures.

1 and 2 designate, respectively, the outer and the inner continuousrails ot' the maintrack.

3 is the inner and 4 the outer siding-rail. The outer siding-railterminates in a rail 16, which is parallel to the main-line rail 2, andthe central portion of which is raised or elevated above the level ofthe main track, the said elevated portion being supported uponsuitably-constructed chairs 1l. A portion ot the main-line rail 2,adjacent tothe elevated rail 1G, is sprung slightly in an outwarddirection, as will be seen at 17, The inner siding- 1ail3 terminates inthe pivoted or movable switch-rail 18, to the inner side of which is Themovable switchrail has an operating-rod 20, which is to be connectedwith and operated by a switch-standot any suitable well-knownconstruction.

The operation and advantages of this invention will be readilyunderstood from the foregoing description, taken in connection with thedrawings hereto annexed. When a train approaches the switch from themain line, when the switch is closed, as shown In Fig. 1 of thedrawings, the movable switchrail will crowd the Wheels in the directionof the outwardly-sprung portionv of the mainline rail 2, and the treadsof the wheels riding upon said rail will thus be caused to ride upon andbe elevated by the elevated rail 16, which is raised suliiciently toenable the wheels to cross the main-line rail 2 without the iianges ofthe wheels coming in contact with the said rail at any point. When therail 2 has been crossed by the wheels, the latter will descend theelevated rail 16 to the level of the siding-rail 4, which forms thecontin nation of the said rail 16. Vhen the switch is open and anapproaching train is desired to continue on the main line, the pivotedswitch-rail, which is now in the position shown in Fig. 2 of thedrawings, will act as a guard-rail to prevent the wheels from ridingupon the raised portion 16 of the siding-rail 4. The outwardly-sprungportion of the mainline rail 2 at the same time serves to afford ampleroom for the flanges of the wheels traveling upon the rail 2 and anample bearin'g for the treads of said wheels, so that there will loe notendency for Ythe latter to tread upon the raised rail. The saidoutwardlysprung rail is thus, as will be seen, useful and essential whenthe switch ls open as Well as when it is closed.

It will be seen that by this invention a switch is provided in which thenecessity for cutting the rails is altogether dispensed with.

Having thus described my invention, what I claim is- The combination ofthe inner main-line rail having an outwardly-sprung portion, the
